Capacitors are must-have components that every engineer needs to build a functioning PCB. In addition, they can store electricity and even charge for the benefit of the board. However, capacitors start to act up when they get damaged. Plus, it''s easy to detect and replace a damaged capacitor with the above steps. Do you have more questions ...
When you witness one or more signals of a damaged capacitor that we mentioned above, you need to prepare to replace the unit. Thus, you will need the following accessories: A tool to open the device casing. Preferably, you should use a HEX wrench or screwdriver. The new capacitor ( you have to match its value with the existing capacitor)
Position the new capacitor leads at the holes where the old capacitor was, with the correct polarity. Just like before, press the tip of the soldering iron directly onto the joint in the back of the circuit board. As soon as the tip falls into the hole, press the wire lead through the hole, then remove the iron.
Tip1: If a capacitor has long enough leads exposed on the front side of the board, you can cut the capacitor off leaving the old leads and solder the new capacitor to the old leads. This method is even faster. See the last picture for an example. Tip 2: You should replace all the electrolytic capacitors, not just the visibly bad ones.
Preferably, you should use a HEX wrench or screwdriver. The new capacitor ( you have to match its value with the existing capacitor) Once you are ready with all of your tools to remove and replace the blown-out capacitor, it’s time to jump into the working steps directly.
The bad capacitor (s) should have markings on the side like for instance 10v 100µf. replace the capacitor (s) With ones with the same markings. You can use a capacitor with the same or higher voltage. But don't change the capacitance. The application you changed the capacitors on should work perfectly now. Did you make this project?
A capacitor is a basic component of a circuit board. It is responsible for storing electrical energy to help the device work properly. The capacitor may get damaged or blown away due to excessive or overheat and over-electricity. At this point, you must replace the capacitor to help the circuit board work properly.
